If you have a key with a security chip in it you will need a bypass module as well

Mine is a 2003 Trailblazer but I believe these work on those as well as the Envoy for a wide range of years.

I took the Viper module and the Smart Start system to a professional installer, they also had to install a bypass as well. I would find a local shop that deals with electronics that can answer the question as to what vehicles the system can be installed on.

Fdeto,A dash install kit, a wiring harness and an antenna adaptor should be all that you need.Eric C

You have a GM vehicle that needs to have an adapter installed with the aftermarket stereo in order to keep certain fucntionality of the stock system. The adapter allows you to retain the OnStar functionality, factory door chimes (required for audible safety warnings), etc. The type of adapter you'll need can be found here: http://www.amazon.com/GMOS-04-OnStar%C2%AE-Interface-Amplified-Systems/dp/B000980HC4/ref=sr_1_1?ie=UTF8&qid=1232998977&sr=8-1

You'll need to purchase a steering servo, 2-channel radio, battery (7.2V with Tamiya connector) and a charger. You'll also need a Phillips-head screwdriver.

I used this part in my 2006 GMC Envoy with auto air controls and it worked fine. You do have to cut wires and reattach them but it was no big deal and didn't take too much time. My system now has all fan speeds and works just fine. Go to Google for an install video if you can, it will help you out.

I have a 2006 GMC Sierra and I didn't need anything extra to install them. Just make sure you gett the correct kit and you shouldn't need anything extra.

I do not know if they fit yoour GMC Envoy 2003 SLT, just I installed those on the rear side of my trialblazer SL 2004. Very easy to install. As far as I know it is not combo is just a model of shock absorber that work fine.

Its Sirius direct connect ready, so you would need the module (sold separately). The kit would then link in the back of the deck.

I have no idea, perhaps call the seller. or write them. We got it for a 2003 Envoy and it also works in a 2007 Yukon.

You will probably need a security bypass, but you should talk to the GMC Dealer to check if you really need the security bypass

Here is the link to the manufacturer's website: http://www.gorancho.com/index.php. Without knowing what you're trying to accomplish, or your specific vehicle information, it is hard to answer that question. I would enter your specific vehicle information into the manufacturer's website, and then see what they suggest for what you're trying to accomplish. Thank you for the inquiry and hope this helps.
